I sell bags like that, actually that person copies my things, but my bags are much larger and are made as carriers but can also be used for bonding. http://www.freewebs.com/thehedgieden...elitemsfor.htm
For siting on the couch with your laptop, all you need is a hedgie bag. When hedgie is at the shy stage or wanting to sleep, they don't try to escape anyways. Once they are coming out of the bag, then it's time to put away the computer and interact with your hedgehog.
